Sta-Kon RF10731 – Frequently Asked Questions
1) Is the Sta-Kon RF10731 rated for 600 volt circuits?
Yes, the RF10731 carries a 600 V rating, which covers standard commercial branch circuits, panelboard and motor connections, and control wiring. It is UL recognized under file E9809.
2) Should I use a nylon insulated ring terminal or a vinyl insulated one for 4 AWG?
Nylon insulation, which is what the RF10731 uses, holds up better to abrasion and higher heat than vinyl and resists cracking when a heavy 4 AWG conductor is flexed at the barrel. Vinyl is the cheaper choice for light-duty, low-flex work. For panel and motor terminations where the lug gets pulled and dressed, nylon is the normal spec.
3) Do I need a special crimp tool for a 4 AWG Sta-Kon ring terminal?
Yes. A 4 AWG copper barrel like the one on the RF10731 is well past the range of a handheld insulated-terminal plier; it needs a heavy-duty crimper with the correct die for the gauge. A hand plier crimp on this size will not give a mechanically sound or electrically reliable termination, and the tool is not supplied with the terminal.
4) Why is this 4 AWG ring terminal yellow?
Yellow is the color code on the nylon insulation of the RF10731, and on insulated terminals the insulation color identifies the wire range. An electrician grabbing yellow on a panel build knows it is the heavy-gauge body rather than the red or blue small-gauge terminals. Useful if you are standardizing a bin system or checking crimps after the fact.
5) Where is the Sta-Kon RF10731 made?
The RF10731 ring terminal is manufactured in Mexico. That matters on jobs with country-of-origin reporting or trade-agreement documentation requirements.
